Bowmalloy 36352 Hex Head Cap Screw 3/8-24 X 3/4 in Grade 9

Product Description

The BOWMALLOY 36352 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. It features a 3/8-24 UNF thread size with a 3/4-inch length under head, manufactured from Grade 9 alloy steel for superior tensile strength over standard Grade 5 or Grade 8 fasteners. A zinc-plated clear chromate finish provides baseline corrosion resistance suitable for indoor and light-exposure environments. Licensed tradespeople and assembly technicians install this fastener where fine-thread engagement and elevated load capacity are required.

This cap screw is suited for applications demanding fine-thread precision and high clamping force, including equipment frames, brackets, drivetrain components, and hydraulic or pneumatic system assemblies. The 3/8-24 fine thread pitch offers greater resistance to loosening under vibration compared to coarse-thread equivalents. It is commonly specified in automotive, heavy equipment, and industrial maintenance contexts where Grade 9 alloy steel performance is a system requirement.

Key Features

• Grade 9 alloy steel construction for high tensile and proof load strength
• 3/8-24 UNF fine thread for precise torque control and vibration resistance
• Fully threaded shank along the 3/4-inch length under head
• Zinc-plated clear chromate finish for corrosion protection in moderate environments
• Hex head drive for standard socket or wrench installation

Compatibility

Designed as a direct-fit fastener for any application requiring a 3/8-24 UNF fully threaded hex head cap screw with a 3/4-inch grip length in Grade 9 alloy steel.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard hex socket or open-end wrench sized to the 3/8-inch hex head. Always verify that the mating thread is 3/8-24 UNF before installation to avoid cross-threading. Apply a thread-locking compound or hardened washer as required by the assembly specification. Follow applicable torque specifications from the equipment manufacturer or relevant industry standard for Grade 9 fasteners.
